Homeland Security Secretary Kirstjen Nielsen also falsely purported the claim that the Trump administration’s tactic of taking children from their families at the border was an enforcement of the law.

There is no law requiring immigrant families to be separated, even if they are crossing the border illegally. Previous administrations allowed families to face deportation proceedings together in civil court.

Nielsen said at a Monday press briefing that she did not hear the recording of the children and referred reporters to the department’s “standards” in treating the kids.

“I would have waited until I was called on to play it, but I was not being called on,” Nuzzi wrote on Twitter. “After another reporter’s phone began loudly ringing with a melodic jingle, I figured the briefing room could probably deal with a more important disturbance.”

Attorney General Jeff Sessions officially announced the change in policy in May, though some cases indicate the practice was in place for months before. The American Civil Liberties Union filed a lawsuit in February on behalf of a Congolese asylum-seeker who was separated from her 7-year-old daughter. The ACLU is seeking a nationwide injunction to stop the Trump administration’s policy, claiming it is a violation of the Fifth Amendment’s right to due process.
